Grid adjustments/Blend with Nvidia Mosaic Displays?
-
I have 5 projectors bundled into a single NVidia mosaic display. This virtual display of course is the full width of my 5 displays, but I was hoping to use the grid calibration tool in Isadora even though they aren't separate devices anymore. Is this possible?

@reload2024 Yes and No.
Nvidia Mosaic is basically doing its job at its GPU level. So it has created a lovely big canvas for you, all edge-blended and lovely. But what you want to do is treat them individually.
A few options:1) Don't use Mosaic? Then you will see everything individually.
2) Treat the output as a big canvas and then use the tools in Isadora to 'cut out' the bits you need. Look at the crop actors, Matte, Matte++ and look at the Virtual Stages for sure. They can be confusing, but use 5 virtual stages and then bring them all back together using "Get Stage Image" and comp them back into your 1 giant stage output.

@skulpture With my video card NVS810 it supports mosaic but not their other edge blend etc tools. I can set the overlap of the projectors but that doesn't do any blending its intended for monitors I guess. So the reason I use mosaic is because when I just use the projectors directly, even with EDID minders plugged into them, all sorts of problems come up. Sometimes these edid minders change their resolution settings for no reason, or I have some obscure problems at critical times and after hours of debugging I find out its the EDID profiles. And if I don't use the EdID minders, windows shuffles up the display order after every reboot. Using Mosaic it keeps perfect track of the displays it always works.
Thanks for the workflow suggestion I'll check it out.

@reload2024 Yup, managing EDID is fun. The high-end media servers (disguise, Pixera, GreenHippo) all manage these with additional hardware and software (one company uses a mini Raspberry Pi hidden away in their cases just to manage EDID).
It sounds like you need/should keep the Mosaic on then. I would use the tools within Isadora to achieve what you need. Might be worth making a template to map out the outputs - if that makes sense? All you are doing really is managing the pixels and where they go. Keep us posted, happy to help if/when I can.
